The First Volume of the Annals of Philosophy being now 

 before the Public, a better opinion of its plan and execution 

 may be formed than we were capable of communicating by any 

 previous prospectus, or introductory plan. Every Number will 

 be found to include four distinct heads: 1. Memoirs on particu- 

 lar branches of science, either original or foreign, and which 

 are presumed to be unknown to most of the readers of the 

 Journal. 2. An accurate and full analysis of some book of 

 science, chiefly the Transactions published by different Pbiloso- 

 phical Societies. 3. Scientific Intelligence. Under this head 

 are included a great variety of important topics, which are, 

 each, too short to constitute a separate essay, but which, not- 

 withstanding, do not constitute the least valuable part of the 

 book. 4. An account of the proceedings of Philosophical 

 Societies. Tbis we conceive to be one of the most valuable 

 departments of our journal. As the accounts are drawn up by 

 the Editor merely from hearing the papers read at tliP different 

 isocieties, mistakes and inaccuracies now and then unavoidably 

 occur; but upon the whole he flatters himself that they are 

 tolerably correct, and they must be of value to those numerous 

 readers who have not access to these societies. Care has been 

 taken to confine these reports to societies of first-rate im- 

 portance. Hitherto the Royal Society, the Linnssan Society, 

 the Wernerian Society, and the French Institute, have alone 

 been noticed ; but for the future we intend also to give regularly 

 the reports of the Geological Society, an institution becoming 

 every day of more importance and value, and which will pro- 

 bably contribute most essentially to an accurate knowledge of 

 the structure of Great Britain. We need not notice the List of 

 Patents and the Meteorological Table, both of which are regu- 

 larly given, and both of which, we flatter ourselves, will be 

 considered as important departments in the Journal. 



All these different departments will naturally improve in value 

 as we go on. This, we flatter ourselves, will already appear to 

 any person who will compare the six numbers of the Annals of 

 'Philosophy already published with each other. 



Some complaints have been made that the number of papers
